APIM download API Providers and API Proxies List from external API Call

[cmiron]

Hello,

I am trying to build a tool to download and transport all API Providers and API Proxies from one tenant to another. For that I want to use the Standard API calls from API Portal /APIProvider and /APIProxy. Those 2 API calls should give me 2 lists of API's that I would then parse and I would transport the API Providers and Proxies one by one.
To use those APIs I need to create an instance in SAP BTP and generate a key, to be used as client credentials. That is the official documentation on how to create the instance credentials: Setting Up OAuth for Cloud Integration in Cloud Foundry | SAP Help Portal.

Once I've done that I should be able to send an external API call with the bearer token generated by the client credentials and I should get the list of providers or proxies that I want. But instead I get a redirect to a page that says "Not Found".

Am I doing something wrong or are the /APIProvider and /APIProxy not working properly?

Thank you very much in advance.

Best Regards,

Constantin

Hello Constantin,
Please check this blog https://blogs.sap.com/2022/03/23/exploring-api-portal-and-api-business-hub-enterprise-apis-of-sap-in...

PS: I would also propose you to evaluate the possibility to use cTMS for API artifacts transport instead of developping your own tool 🙂

Hi Bruno,

Thanks for such a quick response. I have tried that previously and all I got was "401 Unauthorized access".

Also, the API calls I'm making are just for the purpose of finding out which credentials should I use. My application uses Project-piper functions for transporting API Providers and API Proxies between tenants, but as I mentioned, I don't know which credentials to send as the apiServiceKey, so I'm just testing with the APIs from the API Portal in Postman.
This is what I get if I put the apiServiceKey that is generated by apiportal-apiaccess key with Project-Piper:

If you have any ideas why would that happen, I would gladly try them.

Thanks in advance.

Best regards,

Constantin

Hello Constantin,

1. Create apiportal-apiaccess instance using the following JSON
   {
   "role": "APIPortal.Administrator"
   }
2. Create a service key SK on this apiportal-apiaccess instance
3. Use SK clientId/clientSecret to fetch a bearer token from SK tokenUrl
4. Using this bearer token : GET on https://SK url/apiportal/api/1.0/Management.svc/$metadata to get the list of Entity sets
   

   

5. GET on https://SK url/apiportal/api/1.0/Management.svc/APIProxies to get the list of API Proxies on your tenant
   

   

6. GET on https://SK url/apiportal/api/1.0/Management.svc/APIProviders to get the list of API providers
   

   

It works perfectly for me.
